Pedestal system and method of controlling rotational and bearing stiffness

Abstract

A pedestal system comprises a base having a lower cylinder and an upper rotatably supported with respect to the lower vertical cylinder. A lower motor is coupled between the lower and upper cylinders to selectively cause rotational motion between the cylinders. Also provided is a top-most horizontal cylinder with a rotating shaft. The shaft has a bearing coupling the top-most horizontal shaft with respect to the upper vertical cylinder. Finally, an upper motor is provided. The upper motor is coupled between the top-most horizontal shaft and upper cylinder to selectively cause a rotational motion between the top-most horizontal shaft and the upper vertical cylinders.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a pedestal system and more particularly pertains to supporting any of a plurality of objects at any of a plurality of angular orientations.[0003]2. Description of the Prior Art[0004]The use of pedestals and supports of known designs and configurations is known in the prior art. More specifically, pedestals and supports of known designs and configurations previously devised and utilized for the purpose of providing variable support for objects through conventional methods and apparatuses are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.[0005]By way of example, U.S. Pat. No. 2,877,459 to Brown discloses an antenna pedestal mount. U.S. Pat. No. 5,453,753 to Cosenza et al discloses a mechan...

AI Technical Summary

Benefits of technology

[0011]A Method for achieving bearing and rotational stiffness is hereby provided. The method comprises several steps in combination. First step is providing a main-shaft having a first end and a second end and a ring gear. The each end of the main-shaft has a bearing seat. The next step is providing an X bearing having a negative clearance. The X bearing is coupled to the bearing seat of the main-shaft. The negative clearance is between about 0.00015 and .0004 inches. The next step is providing a Conrad bearing. The Conrad bearing is coupled to the second end of the main-shaft. The next step is providing a motor having a drive shaft with a drive gear. The motor has a turning rate of between about 2000 and 8000 RPM. The next step is providing a gear shaft. The gear shaft has a reduction gear and a worm gear coupled thereto. The reduction gear engages with the drive gear of the drive shaft and having a reduction rate of between about 2:1 and 5:1. The worm gear engages to the ring gear of the main shaft. The worm gear and the ring gear have a reduction rate of between about 100:1 and 400:1. The aforementioned steps allow for a gear reduction. The gear reduction allows the turning of the ring gear at a rate of between about 2 and 20 RPM resulting in the worm gear and the ring gear having a high stiffness and the bearings having a high stiffness, thereby providing for a high rotational stiffness.

[0015]It is therefore an object of the present invention to provide a new and improved pedestal system which has all of the advantages of the prior art pedestals and supports of known designs and configurations and none of the disadvantages.

[0016]It is another object of the present invention to provide a new and improved pedestal system which may be easily and efficiently manufactured and marketed.

[0017]It is further an object of the present invention to provide a new and improved pedestal system which is of durable and reliable constructions.

[0018]An even further object of the present invention is to provide a new and improved pedestal system which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such pedestal system economically available to the buying public.

Problems solved by technology

While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a pedestal system that allows supporting any of a plurality of objects at any of a plurality of angular orientations.
